or respirator must be capable of ﬁ ltrating particles

generated by your operation. Prolonged exposure

to high intensity noise may cause hearing loss.

• Keep bystanders a safe distance away from

work area. Anyone entering the work area must

wear personal protective equipment. Frag-

ments of workpiece or of a broken accessory may

ﬂ y away and cause injury beyond immediate area

of operation.

• Hold the power tool by insulated gripping

surfaces only, when performing an operation

where the cutting accessory may contact hid-

den wiring. Contact with a “live” wire will also

make exposed metal parts of the power tool “live”

and could give the operator an electric shock.

• Never lay the power tool down until the acces-

sory has come to a complete stop. The spinning

accessory may grab the surface and pull the pow-

er tool out of your control.

• Do not run the power tool while carrying it at

your side. Accidental contact with the spinning

accessory could snag your clothing, pulling the ac-

cessory into your body.

• Regularly clean the power tool’s air vents. The

motor’s fan will draw the dust inside the housing

and excessive accumulation of powdered metal

may cause electrical hazards.

• Do not operate the power tool near ﬂ ammable

materials. Sparks could ignite these materials.

• Do not use accessories that require liquid cool-

ants. Using water or other liquid coolants may re-

sult in electrocution or shock.

Kickback and Related Warnings

Kickback is a sudden reaction to a pinched or

snagged rotating wheel, backing pad, brush or

any other accessory. Pinching or snagging causes

rapid stalling of the rotating accessory which in turn

causes the uncontrolled power tool to be forced in

the direction opposite of the accessory’s rotation at

the point of the binding.

For example, if an abrasive wheel is snagged or

pinched by the workpiece, the edge of the wheel

that is entering into the pinch point can dig into the

surface of the material causing the wheel to climb

out or kick out. The wheel may either jump toward or

away from the operator, depending on direction of

the wheel’s movement at the point of pinching. Abra-

sive wheels may also break under these conditions.

Kickback is the result of power tool misuse and/or

incorrect operating procedures or conditions and

can be avoided by taking proper precautions as

given below.

• Maintain a ﬁ rm grip on the power tool and posi-

tion your body and arm to allow you to resist

kickback forces. Always use auxiliary handle,

if provided, for maximum control over kickback

or torque reaction during start-up. The operator

can control torque reactions or kickback forces, if

proper precautions are taken.

• Never place your hand near the rotating acces-

sory. Accessory may kickback over your hand.

• Do not position your body in the area where

power tool will move if kickback occurs. Kick-

back will propel the tool in direction opposite to the

wheel’s movement at the point of snagging.

• Use special care when working corners, sharp

edges etc. Avoid bouncing and snagging the

• This power tool is intended to function as a

grinder, sander, wire brushing or cut-off tool.

Read all safety warnings, instructions, illus-

tr ations and speciﬁ cations provided with this

power tool. Failure to follow all instructions listed

below may result in electric shock, ﬁ re and/or seri-

ous injury.

• Operations such as polishing are not recom-

mended to be performed with this power tool. Op-

erations for which the power tool was not designed

may create a hazard and cause personal injury.

• Do not use accessories which are not speciﬁ -

cally designed and recommended by the tool

manufacturer. Just because the accessory can

be attached to your power tool, it does not assure

safe operation.

• The rated speed of the accessory must be at

least equal to the maximum speed marked on

the power tool. Accessories running faster than

their rated speed can break and ﬂ y apart.

• The outside diameter and the thickness of your

accessory must be within the capacity rating

of your power tool. Incorrectly sized accessories

cannot be adequately guarded or controlled.

• Threaded mounting of accessories must match

the grinder spindle thread. For accessories

mounted by ﬂ anges, the arbour hole of the ac-

cessory must ﬁ t the locating diameter of the

ﬂ ange. Accessories that do not match the mount-

ing hardware of the power tool will run out of bal-

ance, vibrate excessively and may cause loss of

control.

• Do not use a damaged accessory. Before each

use inspect the accessory such as abrasive

wheels for chips and cracks, backing pad for

cracks, tear or excess wear, wire brush for

loose or cracked wires. If power tool or acces-

sory is dropped, inspect for damage or install

an undamaged accessory. After inspecting and

installing an accessory, position yourself and

bystanders away from the plane of the rotating

accessory and run the power tool at maximum

no-load speed for one minute. Damaged acces-

sories will normally break apart during this test time.

• Wear personal protective equipment. Depend-

ing on application, use face shield, safety

goggles or safety glasses. As appropriate,

wear dust mask, hearing protectors, gloves

and workshop apron capable of stopping small

abrasive or workpiece fragments. The eye pro-

tection must be capable of stopping ﬂ ying debris

generated by various operations. The dust mask

SPECIFIC SAFETY RULES

PERSONAL SAFETY

GENERAL POWER TOOL SAFETY WARNINGS

WORK AREA SAFETY

ELECTRICAL SAFETY

• Keep work area clean and well lit. Cluttered or

dark areas invite accidents.

• Do not operate power tools in explosive atmos-

pheres, such as in the presence of ﬂ ammable

liquids, gases or dust. Power tools create sparks

which may ignite the dust or fumes.

• Keep children and bystanders away while oper-

ating a power tool. Distractions can cause you to

lose control.

• Power tool plugs must match the outlet. Never

modify the plug in any way. Do not use any

adapter plugs with earthed (grounded) power

tools. Unmodiﬁ ed plugs and matching outlets will

reduce risk of electric shock.

• Avoid body contact with earthed or grounded

surfaces such as pipes, radiators, ranges and

refrigerators. There is an increased risk of electric

shock if your body is earthed or grounded.

• Do not expose power tools to rain or wet condi-

tions. Water entering a power tool will increase the

risk of electric shock.

• Do not abuse the cord. Never use the cord for

carrying, pulling or unplugging the power tool.

Keep cord away from heat, oil, sharp edges

or moving parts. Damaged or entangled cords

increase the risk of electric shock.

• When operating a power tool outdoors, use an

extension cord suitable for outdoor use. Use of

a cord suitable for outdoor use reduces the risk of

electric shock.

• If operating a power tool in a damp location is

unavoidable, use a ground fault circuit inter-

rupter (GFCI) protected supply. Use of an GFCI

reduces the risk of electric shock.

• Do not overreach. Keep proper footing and bal-

ance at all times. This enables better control of the

power tool in unexpected situations.

• Dress properly. Do not wear loose clothing or

jewellery. Keep your hair, clothing and gloves

away from moving parts. Loose clothes, jewellery

or long hair can be caught in moving parts.

• If devices are provided for the connection of

dust extraction and collection facilities, ensure

these are connected and properly used. Use of

dust collection can reduce dust-related hazards.

WARNING READ ALL SAFETY WARNINGS AND ALL INSTRUCTIONS. Failure

to follow the warnings and instructions may result in electric shock, ﬁ re and/or serious

injury. Save all warnings and instructions for future reference. The term "power

tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated

(cordless) power tool.

POWER TOOL USE AND CARE

• Do not force the power tool. Use the correct

power tool for your application. The correct power

tool will do the job better and safer at the rate for

which it was designed.

• Do not use the power tool if the switch does not

turn it on and off. Any power tool that cannot be

controlled with the switch is dangerous and must

be repaired.

• Disconnect the plug from the power source and/

or the battery pack from the power tool before

making any adjustments, changing accessories,

or storing power tools. Such preventive safety

measures reduce the risk of starting the power tool

accidentally.

• Store idle power tools out of the reach of chil-

dren and do not allow persons unfamiliar with

the power tool or these instructions to operate

the power tool. Power tools are dangerous in the

hands of untrained users.

• Maintain power tools. Check for misalignment or

binding of moving parts, breakage of parts and

any other condition that may affect the power

tool’s operation. If damaged, have the power tool

repaired before use. Many accidents are caused

by poorly maintained power tools.

• Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting edges

are less likely to bind and are easier to control.

• Use the power tool, accessories and tool bits

etc. in accordance with these instructions, tak-

ing into account the working conditions and the

work to be performed. Use of the power tool for

operations different from those intended could result

in a hazardous situation.

• Stay alert, watch what you are doing and use

common sense when operating a power tool. Do

not use a power tool while you are tired or under

the inﬂ uence of drugs, alcohol or medication. A

moment of inattention while operating power tools

may result in serious personal injury.

• Use personal protective equipment. Always

wear eye protection. Protective equipment such

as dust mask, non-skid safety shoes, hard hat, or

hearing protection used for appropriate conditions

will reduce personal injuries.

• Prevent unintentional starting. Ensure the

switch is in the off-position before connecting

to power source and/or battery pack, picking

up or carrying the tool. Carrying power tools with

your ﬁ nger on the switch or energising power tools

that have the switch on invites accidents.

• Remove any adjusting key or wrench before

turning the power tool on. A wrench or a key left

attached to a rotating part of the power tool may

result in personal injury.

SERVICE

• Recharge only with the charger speciﬁ ed by the

manufacturer. A charger that is suitable for one type

of battery pack may create a risk of ﬁ re when used

with another battery pack.

• Use power tools only with speciﬁ cally desig-

nated battery packs. Use of any other battery

packs may create a risk of injury and ﬁ re.

• When battery pack is not in use, keep it away

from other metal objects like paper clips, coins,

keys, nails, screws, or other small metal objects

that can make a connection from one terminal

to another. Shorting the battery terminals together

may cause burns or a ﬁ re.

• Under abusive conditions, liquid may be ejected

from the battery; avoid contact. If contact ac-

cidentally occurs, flush with water. If liquid

contacts eyes, additionally seek medical help.

Liquid ejected from the battery may cause irritation

or burns.

• Have your power tool serviced by a qualiﬁ ed

repair person using only identical replacement

parts. This will ensure that the safety of the power

tool is maintained.

• Do not attach a saw chain woodcarving blade

or toothed saw blade. Such blades create fre-

quent kickback and loss of control.

Safety Warnings Speciﬁ c for Grinding and Abra-

sive Cutting-Off Operations:

• Use only wheel types that are recommended

for your power tool and the speciﬁ c guard de-

signed for the selected wheel. Wheels for which

the power tool was not designed cannot be ade-

quately guarded and are unsafe.

• The grinding surface of centre depressed

wheels must be mounted below the plane of

the guard lip. An improperly mounted wheel that

projects through the plane of the guard lip cannot

be adequately protected.

• The guard must be securely attached to the

power tool and positioned for maximum safety,

so the least amount of wheel is exposed to-

wards the operator. The guard helps to protect

operator from broken wheel fragments and

acci-

dental contact with wheel.

• Wheels must be used only for recommended

applications. For example: do not grind with

the side of cut-off wheel. Abrasive cut-off wheels

are intended for peripheral grinding, side forces ap-

plied to these wheels may cause them to shatter.

• Always use undamaged wheel ﬂ anges that are

of correct size and shape for your selected

wheel. Proper wheel ﬂ anges support the wheel

thus reducing the possibility of wheel breakage.

Flanges for cut-off wheels may be different from

grinding wheel ﬂ anges.

• Do not use worn down wheels from larger pow-

er tools. Wheel intended for larger power tool is

not suitable for the higher speed of a smaller tool

and may burst.

Additional Safety Warnings Speciﬁ c for Abra-

sive Cutting-Off Operations:

• Do not “jam” the cut-off wheel or apply exces-

sive pressure. Do not attempt to make an ex-

cessive depth of cut. Overstressing the wheel

increases the loading and susceptibility to twisting

or binding of the wheel in the cut and the possibility

of kickback or wheel breakage.

• Do not position your body in line with and be-

hind the rotating wheel. When the wheel, at the

point of operation, is moving away from your body,

the possible kickback may propel the spinning

wheel and the power tool directly at you.

• When wheel is binding or when interrupting a

cut for any reason, switch off the power tool

and hold the power tool motionless until the

wheel comes to a complete stop. Never attempt

to remove the cut-off wheel from the cut while

the wheel is in motion otherwise kickback may

occur. Investigate and take corrective action to

eliminate the cause of wheel binding.

• Do not restart the cutting operation in the work-

piece. Let the wheel reach full speed and care-

fully reenter the cut. The wheel may bind, walk

up or kickback if the power tool is restarted in the

workpiece.

• Support panels or any oversized workpiece to

minimize the risk of wheel pinching and kick-

back. Large workpieces tend to sag under their

own weight. Supports must be placed under the

workpiece near the line of cut and near the edge of

the workpiece on both sides of the wheel.

• Use extra caution when making a “pocket cut”

into existing walls or other blind areas. The pro-

truding wheel may cut gas or water pipes, electrical

wiring or objects that can cause kickback.

Safety Warnings Speciﬁ c for Sanding Operations:

• Do not use excessively oversized sanding disc

paper. Follow manufacturers recommenda-

tions, when selecting sanding paper. Larger

sanding paper extending beyond the sanding pad

presents a laceration hazard and may cause snag-

ging, tearing of the disc or kickback.

Safety Warnings Speciﬁ c for Wire Brushing Op-

erations:

• Be aware that wire bristles are thrown by the

brush even during ordinary operation. Do not

overstress the wires by applying excessive

load to the brush. The wire bristles can easily

penetrate light clothing and/or skin.

• If the use of a guard is recommended for wire

brushing, do not allow any interference of the

wire wheel or brush with the guard. Wire wheel

or brush may expand in diameter due to work load

and centrifugal forces.

Additional Safety Warnings

• Maintain labels and nameplates. These carry

important information. If unreadable or missing,

contact a MILWAUKEE service facility for a free

replacement.

• WARNING: Some dust created by power sanding,

sawing, grinding, drilling, and other construction

activities contains chemicals known to cause can-

cer, birth defects or other reproductive harm.

Some examples of these chemicals are:

• lead from lead-based paint

• crystalline silica from bricks and cement and

other masonry products, and

• arsenic and chromium from chemically-treated

lumber.

Your risk from these exposures varies, depending

on how often you do this type of work. To reduce

your exposure to these chemicals: work in a well

ventilated area, and work with approved safety

equipment, such as those dust masks that are spe-

cially designed to ﬁ lter out microscopic particles.

Installing Side Handle

The side handle may be installed on either side of

the gear case. Position the side handle in the loca-

tion which offers best control and guard protection.

To install, thread side handle into side handle socket

and tighten securely.

WARNING Only use accessories with

Maximum Safe Operating Speed rated at least

equal to the maximum speed marked on the

power tool. This speed is based on the strength

of the wheel, allowing for a reasonable mea-

sure of safety. It is not meant to imply a best or

most efﬁ cient operating speed. Do not exceed

the Maximum Safe Operating Speed.

Installing/Removing Accessories

Make sure the wheel does not extend beyond the

bottom of the guard. Threaded hub grinding wheels

may require a deeper guard (see "Accessories").

1. Remove the battery pack.

2. Properly position the guard (Fig. 2).

Controlled Start

The controlled start feature reduces the torque

reaction "jerk" when its trigger is pulled.

Electric Brake

The electric brake engages when the switch is

released, causing the wheel to stop within sec-

onds. There may be a delay between the time the

switch is released and when the brake engages.

Occasionally the brake may miss completely. If the

brake misses frequently, have the tool serviced by

an authorized MILWAUKEE service facility. Make

sure the tool comes to a complete stop before

laying it down.

Paddle Switch Operation

To start the tool, grasp the handle and side handle

ﬁ rmly. Push the lock-off button forward and squeeze

the paddle switch.

To stop the tool, release the paddle switch. Make

sure the tool comes to a complete stop before lay-

ing the tool down.

General Operation

1. If you have just installed an accessory or are

beginning a period of work, test it by letting it

spin for one minute before applying it to the

workpiece. Out-of-balance or damaged acces-

sories can mar workpiece, damage the tool, and

cause stress that may cause accessory failure.

2. Use a clamp, vise or other practical means to

hold your work, freeing both hands to control

the tool.

3. Hold tool securely with both hands.

4. Start the tool.

Note: If the battery is inserted when the tool

switch is in the “ON” position, the tool will not run.

Turn the tool off, then back on to begin work..

5. Allow accessory to come to full speed before

beginning work.

6. Control pressure and surface contact between

accessory and workpiece. Too much pressure

slows speed.

7. When ﬁ nished, turn off the tool and make sure it

comes to a complete stop before laying it down.

USING GRINDING WHEELS

Grinding and cut-off wheels should NOT be

dropped, rolled or bumped.

Discard wheels that have been dropped, rolled,

bumped, subjected to extreme changes in tempera-

ture, or come into contact with solvents or wetness.

Grinding

When grinding, hold tool at a 5

to 15

angle, using

constant pressure for a uniform ﬁ nish. Too great an

angle causes concentrated pressure on small areas

which may gouge or burn work surface.

Wire Wheel Brush

Fig. 7

WARNING Everyone in the area must

wear protective clothing and safety goggles

or face shields. Fatigued wires and residue

will ﬂ y off the brush with considerable force,

causing potential for serious injury.

USING WIRE BRUSHES

Wire brushes are useful for removing rust, scale,

burrs, weld slag, etc.

Always install wire cup brushes according to the

accessory manufacturer’s instructions.

When using a wire wheel brush, install guard ac-

cording to "Installing/Removing Accessories".

WARNING Because the wires on wire

wheel brushes are directed towards the op-

erator, a guard must be used to protect the

operator when fatigued wires break.

Fig. 4

WARNING A Type "1" guard must be

installed when using a cut-off wheel to provide

maximum protection for the operator if the

wheel should break.

WARNING Using the face of a Cut-Off

Wheel (as in grinding) will cause the Wheel

to crack and break, resulting in serious per-

sonal injury.

USING CUT-OFF WHEELS

Type "1" Cut-Off Wheels are suited for small cut-off

and shallow notching operations only.

When using a cut-off wheel, hold the tool as shown,

using only the edge of the wheel.

Grinding Wheel Selection

Use grinding wheels, and accessories that are:

• correct size as written on tool’s nameplate.

• rated at or above the RPM listed on the tool’s

nameplate.

• correct accessory, wheel type and grit for the job.

Grinding is the cutting action of thousands of abra-

sive grains on the face of a grinding wheel. When

grinding metals such as steel and iron, choose an

aluminum oxide grinding wheel. Select a silicon

carbide grinding wheel for stone and concrete. Use

cotton reinforced wheels for non-ferrous metals.

Type 27 Reinforced 1/8" thick or less Cut-Off

Wheels are suited for small cut-off and shallow

notching operations only. Always handle wheels

carefully to avoid damage. Before installing any

wheel, always inspect it for cracks. If wheel is

cracked, discard it to prevent others from using it.

Care of Grinding & Cut-Off Wheels

Grinding/cut-off wheels should be protected from:

• wetness and extreme humidity

• any type of solvent

• extreme changes in temperature

• dropping and bumping

Grinding and cut-off wheels should be stored:

• in an organized way so wheels can be removed

without disturbing or damaging other wheels

• with their safety information

Tightening tab

WARNING Never exceed Maximum

Safe Operating Speed of brush. Do not use

a damaged brush or one that is functioning

improperly (throwing wires, out-of-balance,

etc.). These conditions increase the pos-

sibility of further brush failure and possible

injury. Discard and replace damaged brushes

immediately.

Test wheel for balance and loose or damaged wires

by letting it spin for one minute before applying it

to the workpiece. During this time, no one should

stand in front of or in line with it.

Control pressure and surface contact between

wheel and workpiece. Too much pressure causes

over-bending of wires and heat build-up caus-

ing premature wire breaking, rapid dulling and

reduced brush life. Instead of more pressure, try

a wire wheel with more aggressive cutting action

(increased wire size, decreased wire length or dif-

ferent brush type (knot type vs. crimped wire type).

Aluminum Oxide

For fast cutting, general purpose discs for most

metal jobs. Best for cold-rolled steel, stainless

steel or metals requiring tough, fast cutting, long

lasting abrasives.

Aluminum Zirconia Bi-Cut

Unique grit pattern is arranged in clusters for fast-

er stock removal and cleaning. Ideal for removing

paint from cars, boats, etc. without clogging.

Ceramic

Lasts up to 3 times longer than Aluminum Ox-

ide Discs. For general metal working. Ideal for

tough jobs.

Sanding Disc Selection

Use sanding discs and accessories that are:

• correct size as written on tool’s nameplate.

• rated at or above the RPM listed on the tool’s

nameplate.

• correct accessory, wheel type and grit for the job.

Refer to the table below to select the correct type

of sanding disc for your job. Generally, use 24 or

36 grit for heavy stock removal; 50, 60, or 80 grit

for medium stock removal and 120 grit for ﬁ nishing.

Always begin with a coarse grit, using successively

ﬁ ner grits to obtain the desired ﬁ nish. See your

MILWAUKEE Electric Tool Catalog for a complete

list of sanding discs.

USING SANDING DISCS

Installing Backing Pad and Sanding Discs

1. Remove the battery pack.

2. Wipe the accessories, disc nut and spindle to

WARNING To reduce the risk of injury,

always unplug the charger and remove the

battery pack from the charger or tool before

performing any maintenance. Never disas-

semble the tool, battery pack or charger.

Contact a MILWAUKEE service facility for

ALL repairs.

Cross Sanding

When ﬁ nishing a surface that has been prepared by

a coarse disc or wheel, sand at right angles to the

strokes made by the coarser disc. Finishing marks

left from previous sanding are easily seen and

removed for a uniform ﬁ nish. Failure to cross sand

when changing from a coarse disc to a ﬁ nishing disc

may result in deep scratches and circular marks.

Removing Welds or Hammer Marks

When removing welds or hammer marks, limit

coarse sanding to the immediate area. Use suc-

cessively ﬁ ner grits to smooth surface.

Finishing Metal

Constantly move across the surface. Work faster on

curved surfaces where contact areas are smaller

and pressure is greater. Flat areas may appear at

the end of the stroke when pressure is too heavy.

Ease up on pressure at end of each stroke and

when reversing strokes.

Troubleshooting

Deep scratches and circular marks can result from:

• Using too coarse a grit

• Using a partially glazed disc

• Dirt or loose metal on the workpiece

• Failure to sand across the grain when changing

from coarse to ﬁ nishing discs

• Failure to use closed coated discs to reduce the

problem of grains working loose and scratching

the workpiece

Bluish discoloration of metal surface indicates:

• Excessive heat caused by circular motion in a

small area

• Excessive pressure

• Use of worn out or glazed discs

RÈGLES DE SÉCURITÉ GÉNÉRALES RELATIVES AUX

OUTILS ÉLECTRIQUES

AVERTISSEMENT LIRE TOUTES LES RÈGLES ET INSTRUCTIONS DE SÉCURITÉ.

Ne pas suivre l’ensemble des règles et instructions peut entraîner une électrocution, un

incendie ou des blessures graves. Conserver les règles et les instructions à des ﬁ ns

de référence ultérieure. Le terme «outil électrique» ﬁ gurant dans les avertissements ci-

dessous renvoie à l’outil électrique à alimentation par le réseau (à cordon) ou par batterie (sans ﬁ l).

• Maintenir la zone de travail propre et bien

éclairée. Les zones encombrées ou mal éclairées

sont favorables aux accidents.

• Ne pas utiliser d’outil électrique dans une at-

mosphère explosive, telle qu’en en présence de

liquides, de gaz ou de poussières inﬂ ammables.

Les outils électriques génèrent des étincelles qui

peuvent enﬂ ammer les poussières ou les fumées.

• Tenir les enfants et les personnes non autorisées

à l’écart pendant le fonctionnement d’un outil

électrique. Un manque d’attention de l’opérateur

risque de lui faire perdre le contrôle de l’outil.

• La ﬁ che de l’outil électrique doit correspondre

à la prise d’alimentation. Ne jamais modiﬁ er la

ﬁ che d’une manière quelconque. Ne pas utiliser

d’adaptateur avec les outils électriques mis à la

terre (à la masse). Des ﬁ ches non modiﬁ ées et des

prises d’alimentation assorties réduisent le risque de

choc électrique.

• Éviter tout contact corporel avec des surfaces

reliées à la masse ou à la terre telles que tuyaux,

radiateurs, cuisinières et réfrigérateurs. Un risque

de choc électrique plus élevé existe si le corps est

relié à la masse ou à la terre.

• Ne pas exposer les outils électriques à la pluie ou

à l’humidité. Le risque de choc électrique augmente

si de l’eau s’inﬁ ltre dans un outil électrique.

• Prendre soin du cordon. Ne jamais utiliser le

cordon pour transporter, tirer ou débrancher

l’outil électrique. Tenir le cordon à l’écart de la

chaleur, des huiles, des arêtes coupantes ou des

pièces en mouvement. Un cordon endommagé ou

emmêlé présente un risque accru de choc électrique.

• Se procurer un cordon d’alimentation approprié en

cas d’utilisation d’un outil électrique à l’extérieur.

L’utilisation d’un cordon d’alimentation pour us-

age extérieur réduit le risque de choc électrique.

• S’il est nécessaire d’utiliser l’outil électrique

dans un endroit humide, installer un appareil

à courant résiduel (RCD). L’utilisation d’un RCD

réduit le risque de décharge électrique.

les blessures.

• Empêcher les démarrages accidentels. S’assurer

que la gâchette est en position d’arrêt avant de

brancher l’outil à une source de courant, d’insérer

la batterie, de le ramasser ou de le transporter.

Le fait de transporter l’outil en gardant le doigt sur

la gâchette ou de le brancher lorsque la gâchette

est en position de marche favorise les accidents.

• Retirer toute clé de réglage avant de mettre l’outil

sous tension. Une clé laissée attachée sur une

pièce mobile de l’outil électrique peut entraîner des

blessures.

• Ne pas travailler à bout de bras. Bien garder un

bon équilibre à tout instant. Ceci permet de mieux

préserver la maîtrise de l’outil électrique dans des

situations imprévues.

• Porter des vêtements adéquats. Ne pas porter de

vêtements amples ni de bijoux. Ne pas approcher

les cheveux, vêtements et gants des pièces en

mouvement. Les vêtements amples, les bijoux ou

les cheveux longs risquent d’être happés par les

pièces en mouvement.

• Si des dispositifs sont prévus pour l’extraction

et la récupération des poussières, vérifier

qu’ils sont connectés et utilisés correctement.

L’utilisation de ces dispositifs peut réduire les risques

liés aux poussières.

SÉCURITÉ INDIVIDUELLE

SÉCURITÉ ÉLECTRIQUE

SÉCURITÉ DU LIEU DE TRAVAIL

UTILISATION ET ENTRETIEN

DE L’OUTIL ÉLECTRIQUE

• Ne pas forcer l’outil électrique. Utiliser l’outil élec-

trique approprié à l’application considérée. L’outil

électrique adapté au projet considéré produira de

meilleurs résultats, dans des conditions de sécurité

meilleures, à la vitesse pour laquelle il a été conçu.

• Ne pas utiliser l’outil électrique si le commuta-

teur ne le met pas sous ou hors tension. Tout outil

électrique dont le commutateur de marche-arrêt est

inopérant est dangereux et doit être réparé.

• Débrancher la ﬁ che de la prise d’alimentation et/

ou la batterie de l’outil électrique avant d’effectuer

des réglages, de changer d’accessoires ou de

ranger l’outil. De telles mesures de sécurité préven-

tive réduisent le risque de mettre l’outil en marche

accidentellement.

• Ranger les outils électriques inutilisés hors de la

portée des enfants et ne pas laisser des person-

nes qui connaissent mal les outils électriques ou

ces instructions utiliser ces outils. Les outils élec-

triques sont dangereux dans les mains d’utilisateurs

non formés à leur usage.

• Entretien des outils électriques. S’assurer de

l’absence de tout désalignement ou de grippage

des pièces mobiles, de toute rupture de pièce

ou de toute autre condition qui pourrait affecter

le bon fonctionnement de l’outil électrique. En

cas de dommages, faire réparer l’outil avant de

l’utiliser de nouveau. Les outils électriques mal

• Être sur ses gardes, être attentif et faire preuve

de bon sens en utilisant un outil électrique. Ne

pas utiliser un outil électrique en cas de fatigue

ou sous l’influence de drogues, d’alcool ou

de médicaments. Un instant d’inattention lors de

l’utilisation d’un outil électrique peut entraîner des

blessures graves.

• Porter l’équipement de protection requis. Tou-

jours porter une protection oculaire. Selon les

conditions, porter aussi un masque anti-poussières,

des bottes de sécurité antidérapantes, un casque

protecteur ou une protection auditive aﬁ n de réduire
